Answer:
Similarity
Both nervous and endocrine system are similar in a way that they perform the regulatory function in the body and act as regulator in various body functions.
Difference
1. nervous system uses electrical impulses (neural)for signaling while endocrine system uses chemical signals called hormones, which travel through the bloodstream and control the actions of cells and organs.
2. The nervous system can respond quickly to stimuli, through the use of action potentials and neurotransmitters. Responses to nervous system stimulation are typically quick but short lived. The endocrine system responds to stimulation by secreting hormones into the circulatory system that travel to the target tissue.

Answer:
I can’t see the answer choices. I would like to guess that it would either be natural selection, or something to do with limited natural recourses.
Brainliest? I’m trying to rank up. Thank you sooo much.
Half life is the time taken by a radioactive isotope to decay by half of its original mass. In this case the half life of carbon-14 is 5500 years.
The original mass is 30 g and the new mass is 3.75 g.
New mass = Original mass × (1/2)^n, where n is the number of half lives;
3.75 = 30 × (1/2)^n
1/8 = (1/2)^n
n = 3
Thus, the time taken will be; 3 × 5500 = 16500 years.
Answer:
- What percent of the population is BB? (Round to two decimal places) → 17% BB
- What percent of the population is Bb? (Round to two decimal places) → 48% Bb
- What percent of the population is bb? (Round to two decimal places) → 35% bb
- What is the frequency of the single dominant allele B? (Round to two decimal places) → 0.41
- What is the frequency of the single recessive allele b? (Round to two decimal places) → 0.59

1. eight
2. four
3. less than
Explanation:
from the data given...
n= 4
where n= # of genes
&, the extreme # of segments= 
Genes, which make up a genotype are instructions for encoding a phenotype, expressed as proteins in translation.
...one gene may have 2 alleles
An allele is an alternate form of a particular gene. Genes can have multiple alleles, but in this case...
∴4 genes= 4 × 2=<u> </u><u>8 segments</u>
<u />
<u>Thus, each allele gives </u> 
= <u>1 segment</u>
